Displacement rates for normal and reverse faults (N = 57) are generally higher when averaged for the Holocene (~10 ka) than for the late Quaternary (~300 ka) and longer time scales. Holocene acceleration of displacement ...

Piton de la Fournaise (La Réunion island) is a very active basaltic volcano, with five eruptions between Nov 2009 and Dec 2010. Pre-eruptive seismic crises usually last
for a few hours and mainly consist of a volcano-tectonic ...

In the Ainsa basin, the Castissent sequence has been subdivided
in two different composite depositional sequences: Castissent-1 (Cs-1) and
Castissent-2 (Cs-2). This study focuses on the lower part of Cs-1, where the
Fosado ...

The 500 m thick Ross Sandstone Formation is well
exposed in sea cliffs facing the Atlantic and along the Shannon Estuary in
western Ireland. It forms the sandy deep-water part of a major
shallowing-upward Pennsylvanian ...

The Ross Formation is well exposed in sea cliffs facing the Atlantic and Shannon estuary
in western Ireland. It forms the sandy deep-water part of a major
shallowing-upward Pennsylvanian succession. Over the last four ...

The Ross Formation is well exposed in sea cliffs
facing the Atlantic and Shannon estuary in western Ireland. It forms the sandy deep-water
part of a major shallowing-upward late Mississippian to Pennsylvanian succession.
Over ...

Displacements on tectonic faults primarily accrue during earthquakes at rates that vary through time. To examine the processes that underlie the temporal changes in fault displacement rates we analyse displacements and ...

Oxygen isotope data for well dated Holocene speleothems from Europe have been compiled for the first time. The data were analysed at 1 ka time slices through the Holocene by taking averages of 50 year duration. After
filtering ...

Normal faults contained in multilayers are often characterised by dip refraction which is generally attributed to differences in the mechanical properties of the layers, sometimes leading to different modes of fracture. ...

Tenerife (Canary Islands, Spain) is a volcanic island dominated by the Teide-Pico Viejo complex, with a summit height of 3718 m. After renewed signs of activity starting in 2004, an active seismic experiment was performed ...

Empirical rock properties and continuum mechanics provide a basis for defining relationships between a variety of mechanical properties, such as strength, friction angle, Young’s modulus, Poisson’s ratio, on the one hand ...

Much of the twentieth century multidecadal variability in the relationship between North Atlantic Oscillation (NAO) and winter climate over the North Atlantic–European sector can be linked to the combined effects of the ...

Magmatic and hydrothermal processes play a significant role in generating seismicity at active volcanoes. These signals can be recorded at the surface and can be used to obtain an insight into the volcano's internal dynamics. ...

Lattice methods are a class of numerical scheme which represent a medium as a connection of interacting nodes or particles. In the case of modelling seismic wave propagation, the interaction term is determined from Hooke′s ...

Sandstone provenance studies can help constrain palaeogeographic reconstructions and ancient drainage system scales and pathways. However, these insights can be obscured by difficulties in geochemically distinguishing or ...

Pb isotopic data from K-feldspars in Middle Triassic (Anisian) sandstones in the Wessex Basin, onshore southwest UK, and the East Irish Sea Basin, some to the north, show that the same grain populations are present. This ...

Few terrestrial Holocene climate records exist from Southeastern Europe despite its important geographic position as a transitional climatic zone between the Mediterranean and mainland continental Europe. In this study we ...

Existing conceptual growth models for faults in layered sequences suggest that faults first localise in strong, and brittle, layers and are later linked in weak, and ductile, layers. We use the Discrete Element Method (DEM) ...

Despite recent technological advances in volcano monitoring, eruption forecasting is
still inadequate. Improved forecasting requires a deeper understanding of when
unrest will lead to an actual eruption. Shallow Long ...
